Review request for Asterisk Developers.


Changes
-------

Corrected description. Option 'm' sends Progress, not Proceeding.


Summary (updated)
-------

This senario is based on an ETSI ISDN installation, but I'm sure applies to others.

option 'r' sends a Ringing Indication to the network, which informs the network we can deliver the call, but ultimately we may not be able to, and need to issue Congestion.
option 'm' sends a Progress Indication, which allows us to indicate Congestion and then let the call go, the network providor can then try the next provider.

The current ugly solution, is to record a music file, of Ringing, and play it, something like.
  exten => 80,1,Dial(DAHDI/2,30,m(myring))
  exten => 80,n,Congestion()

This patch provides an optional argument for option 'r' as in 'r(vodaring)'

Now a tidy and customizable way to play out any tones from the indications.conf file like.
  exten => 80,1,Dial(DAHDI/2,30,r(vodaring))
  exten => 80,n,Congestion()


This addresses bug 14504.
